When the waves of the Lancang River merge into the warm current of the Mekong River, a steel artery is piercing through the humid and hot monsoon of the Indochinese Peninsula. As the bidding for the track and four electric engineering projects begins, the China Thailand high-speed railway bids farewell to the silence of civil engineering excavation and officially enters a critical period of track laying and network construction, heading towards the 2030 opening agreement at full speed.

Recently, the procurement platform of China Railway Group released the pre qualification announcement for the total price contracting construction of the Bangkok to Nakhon Ratchasima section of the China Thailand high-speed railway cooperation, which means that after many years of construction, the project has officially entered the stage of track supporting and electromechanical system construction.

Basic conditions for project bidding

The first phase of the Bangkok Nakhon Ratchasima high-speed railway project has signed Contract No. 2.3 between the two parties in October 2020. The owner is the State Railway Corporation of Thailand, and the construction funds are allocated by the Thai government. The funds are implemented and the design plan is complete. The bidding unit is China Railway International Thailand Branch. The project has met the statutory bidding conditions and is open for pre qualification application to eligible enterprises.

The project is divided into four major sections for construction

This bidding is divided into four independent sections, each with its own focus on construction scope: ZTGD-1 section covers the distance from Apiwa Central Station to DK119+008.5, responsible for supporting projects such as track laying, sleeper prefabrication, track fine adjustment, and rail polishing for the entire line in the front section, and 244.3 kilometers of track laying for the main line; ZTGD-2 section undertakes the construction of the second half of the track to Nakhon Ratchasima Station, completing the laying of 268.5 kilometers of main track, excluding the prefabrication of sleepers and the unified polishing and surveying work of the entire line; ZTQD section is responsible for the electrification supporting projects such as traction substations, contact networks, and power distribution for the entire line; The ZTRD section is responsible for the construction of weak current systems such as communication, signaling, scheduling, ticketing, and disaster monitoring for the entire line.

Clear qualification threshold for bidding enterprises

The bidding enterprises for two sections of track construction need to have the special qualification of engineering general contracting and the first level professional qualification of railway track laying and beam erection; Electrification sections require holding both first level qualifications in railway electrification and railway electrical services; The communication signal section needs to have the first level qualifications for railway electrical services and electronic intelligence.
